DAMPING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 363,326, dated May 17,1887.

Application filed October 11, 1886. Serial No. 215,924. (No model.)

To all whom it may concern.-

Be it known that we, FREDERICK L. Goss and SAM G. Goss, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Damping -Machines; and we hereby declare the following to be a full, clear, and exact description of the same. 2

' Our invention relates to a machinefor dampening paper preparatory to printing upon it, the leading objects being to provide for the convenient handling of ponderous rolls of paper in the process of dampening and to effect uniform and rapid dampening of the paper.

To this end our invention consists in the general construction of a machine for trans- I ferring the paper from its initial roll to sec- 0nd roll, directing againstit betwee'nthe rolls during the transfer a continuous spray of water extending across its entire .width, and for discharging the dampened roll; and itfurther consists in certain details of construction and combinations of parts, allas hereinafter more fully set forth. y

In the drawings, Figure l is a side elevation of our improved machine; Fig. 2, a similar view of abroken portion of the same, partly in section, illustrating by dotted lines the operation of discharging a roll dampened while it was being wound; Fig. 3, a central longitudinal broken section of the device; Fig. 4, a broken sectional view taken on the line 4. 4. of Fig. 1, and Fig. 5 abroken sectional view taken on the line 5 of Fig. 1. 1

A is the frame of the machine, provided with suitable extensions and bearings to support the parts hereinafter described.

B is a roll of dry paper. Rolls come from the paper-mill, are commonly of a uniformor substantially uniform size, and are wound upon hollow metal shafts or spools t. Preparatory to placing a roll, B, in its operative positionupon the machine, ashaft, s, of a size and length to fit into the bearings s on opposite sides of the machine, is passed through the spool t in a manner to extend a distance beyond the spool at each end. To insure the centering of the roll upon theshaft s, movable 5c cone-shaped stops 1', Fig. 5, are provided upon B, as they the shaft 8, one toenter' each end of the spool 15, the stops being held in place by set-screws r. The stops r, it will be seen, perform the double function of centering the roll upon its bearings and preventing its shifting toward either side of the machine. To avoid thev necessity of lifting the roll B into its bearings s, an extension,'q, is provided on each side of the machine. The upper surfaces of the extensions q incline from the sides of the bearings s to a point in line with or below the center of the roll B as it lies upon the floor, and form guides for the shaft 8, upon which to roll the same until it drops into the bearings s, when the roll B occupies its position upon the ma chine. l I

Between the roll 13 and a drum, 1), hereinafter described, is a coverless water tight trough-or douchepan, 0, supported to extend transversely'across the machine, being tilted, as shown, and having an outlet, 1). Toward the bottom of the douche-pan, and at the side of the same nearest the roll B, a perforated water-pipe, 0, closed at one end, isprovided, to

extend longitudinally ofv the douche-pan and through bearings n at each end of the same.

The perforations 0 in the water-pipe extend along the pipe from one end of the douchepan to the other, and are arranged todirect parallel streams.

lhe open end of the pipe 0 is connected to a water-supply by means of a suitable loose coupling of common construction (not shown) in a manner to enable the pipe 0 to be turned in its bearings to change the direction of the streams,the pipe being fastened in any adjusted position by means of a set-screw, a, in the bearing a. Toward the side of the douchepan, opposite the pipe 0 and running parallel with the same, is an adjustable deflector or spattering-board, G, pivoted at each end to the adjacent end of the douche-pan. A stream of water from the perforations in the Water-pipe -'o, directed against the spattering-board G, is

deflected to any desired angle by the proper adjustment of the spattering-board, which is held in its adjust-ed position by the thumbscrew' 2', and a spray of water of any required density can thus be deflected against the paper which passes across the douchepan, as hereinafter described. Between the roll -B and driving-shaft m, to which it is keyed, is the drum or roller D, extending transversely across the machine, the driving-shaft at being. suitably journaled upon brackets Z on each side of the frame A, and receiving its motion from the drivingpulley 7c. The purpose of the drum D is to rotate the damp-paper spool E, as hereinafter described.

Thespool E has itsbearings between guide.- arms F F of the pivotal brackets I,- arranged on each side of the machine, and in its normal position the sp' ol rests upon the drum D, the

journal ends of the spool extending slightly beyond the outer sides of the arms, for a purpose hereinafterdescribed.

The operation of our machine thus far described is as follows: A roll of dry paper, B, wound upon its spool t, is adjusted upon the shafts and placed in position upon the ma chine, all as hereinbefore described, and in a manner to allow the paper to unwind from the under side of the roll, as shown. The loose end of the web upon the roll B is then passed over the roller j, thence over and across the douche-pan O, and under and around the drum D to the spool E, upon which it is fastened, the roller j, douche-pan, and drum being arranged with relation to each other to allow the webof paper to'pass across the opening of the douche-pan on an inclined plane parallel (or nearly so) with the-bottom of thelatter, The water-pipe o is adjusted to cause a stream of water from the perforations oto strike against the spattering-board and be deflected upward in a spray of the proper density by the adjustment of the spattering-board, as before described,

and dampen the web. The machine being set- 1n mot1on,the friction of the rotating drum D against the web, which passes around-it and against the spool E, (first, and after the first revolution of the spool the web upon the same,) causes the paper to unwind from the I roll B upon the spool E,to form the dampened roll E. The increase in circumference of the roll E, as it rests upon the drum D, causes the spool g: Bt o rise in its bearings between the arms Pivoted to the outer side at the upper end of each arm-F is-abracket, H, provided with curved fingers h h, the spaces between the fin- V gers forming sockets h, to receive the journal ends of the spool E, as hereinafter described. In the normal position of the brackets H (see Fig. 1) the fingers h extend across the openings, while the fingers h hang vertically downward along the arm F in rear of the opening. In its rise toward the upper ends of the arms F (which are somewhat shorter than the arms F) the ends of the spool E (projecting beyond thesides of the arms F F, as before described) come into contact with the fingers h and cause beveled surfaces of the spring-catches force them inward, causing the catches to spring out when passed and present shoulders for the fingers h to rest upon. When the fingers h have passed the springcatches g, the roll E is of a size equal to the capacity of the machine, at which point it is necessary to stop the machinery and discharge the roll, which latter operation is accomplished in the followin g-manner: The brackets I, carrying the arms F F, before described, are keyed upon a shaft, 1, which is journaled upon the frame A behind the driving-shaft m. The shaft f projects beyond the frame A, (on the side of the machine opposite to the driving-pulley,) and keyed to the shaft f, at its end thus projecting, 1s a large projections L of the frame .A. Keyed to the sameshaft and adjacent to the cog-wheehK 1s the lever M, provided at its upper end with a suitable lateral handle. (Not shown.) To discharge the roll the lever M is turned in the proper direction to cause the cog-wheel K to rotate the cog-wheel J in the opposite direction and with it the brackets I. When the arms F F reach the position indicated by dotted lines in Fig. 2, the spool E rolls out of the sockets h, and the roll E drops upon the floor.

To adjust the bracket I again in its normal position, the lever M is turned in the opposite IOO direction until stopped by the contact of the 1 projections I on the brackets I with the projections L, the latches 6, when adjusted, serving to keep the projections I and L rigidly together, and thus sustain the brackets I.
